STAMP-GANGELING DEVICE.

Application filed January 8,

T 0 all whom it may concern:

Be it known that I, CHARLES H. SAMBERG, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Stamp-Canceling Device; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it app'ertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to letter stamping and stamp canceling devices of the hammer type and has for its object the provision in a device of this character of improved means for adjusting the stamp-head relative to its carrying handle to compensate for a wearing of the threads which connect the die and stamp-head, whereby the stamp canceling and date marks may always be disposed transversely of the handle in convenient position for striking a letter instead of gradually working around relative to the handle as the connecting threads of the head and die wear, due to. the frequent separation of such parts to change the time and date designations in the die.

The invention is fully described in the following specification, and While, in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a perspective view of a stamp embodying my invention. Fig. 2 is an enlarged side view of the head portion thereof with parts in section. Fig. 3 is a plan of the stamp carrying end of the handle, and Fig. 4: is a perspective view of the adjusting washer and lock.

Referring to the drawings, 1 designates the stamp head, 2 the die, which is customarily threaded into said head, as shown, and 3 the handle of a stamp embodying the invention. A stud 4 projects axially from the top of the stamp-head for fitting into an aperture in the handle, and the head is clamped to the handle by a nut 5 by threading onto said stud. With this form of stamp it is found that the frequent separation and reuniting of the die and stamp-head to change the time and date designations, which change usually occurs every half hour,

causes a gradual wearing of the threads so that the die when tightened into the head will have its position gradually changed relative thereto and prevent a convenient stamping of a letter or other article in proper form. To obviate this objectionable feature I square or otherwise irregularly form the base portion of the stud 4 to the depth of a washer 6, as shown at 7 and then place a washer 6 thereover, it being provided with a complemental opening 8 for such purpose. The handle 3 is then intended to have its circular opening 9 fitted over the stud 4 to turn freely thereon, and is provided around such opening with a segmentally arranged series of apertures 10, which are concentric to the opening 9 and into any one of which a laterally projecting stud or spur 11 on the washer 6 may project. A washer 12 is preferably interposed between the handle and nut 5 to cooperate with the nut to clamp the handle to the head 1 and against the interposed lock-washer 6. The washer 12 is preferablyof suitable size to cover the handle apertures 10. The handle 3 is preferably of spring steel to adapt it to have a resilient action when in use so as to eliminate jar from the hand of the operator and also to permit a springing of the stamphead to adjust itself to the surface struck. The apertures 10 in the handle preferably are arranged in semi-circular form about the stud opening 9 as indicated in Fig. 3. It is apparent with this manner of fastening the stamp-head to the handle that upon a rela' tive turning of the die from normal or proper position relative to the handle, due to a wearing of its threads or from any other cause, the head and attached die may be quickly adjusted relative to the handle by simply releasing the nut 5 from clamping engagement with the handle sufiiciently to permit a turning of the handle relative to the washer 6 to place the washer spur 11 into a desired one of the handle apertures 10, after which the nut is again tightened to rigidly attach the stamp-head and handle with the washer 6 locking them against relative rotary movements. The arrangement of the handle apertures 10 permits a step by step adjustment of the washer 6 and handle to compensate for a gradual wearing of the interengaging portions of the stamp-head and die, and when the washer spur has been adjusted throughout the entire are described by the apertures 10 the handle can be inverted relative to the stamp-head to permit a continued step by step adjustment of the washer and handle to complete a revolution of adjustment.

It is evident that I have provided a simple and efiicientmeans for relatively adjusting the stamp-head and handle and locking the same in adjusted positions, and that it permits a quick and easy adjustment of the parts as desired.

I wish it understood that my invention is not limited to. any specific construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thusIdescribed my invention, what I claim as new and desire to secure by Let-- ters Patent, is,

1. In a stamp of the class described, a stamp-head having a stud projecting therefrom, a spur projecting from the head adjacent to and in the direction of projection of said stud, a handle having an opening for rotatably fitting over said stud and hav ing a plurality of apertures concentric to said opening and into any one of which said spur may project, and means cooperating with the stud to clamp the handle in adjusted position to the head.

2. In a stamp of the class described, a stamp-head having a stud projecting therefrom with its base of irregular form in cross section, a handle having an opening for rotatably receiving said stud and having a semi-clrcular series of apertures arranged concentric to said opening, a nut threaded to the stud for clamping the handle to the head, and a member fitted to the irregular base portion of the stud and having a spur for fitting into any one of said handle apertures to retain the handle and stamp-head locked in adjusted relation when clamped together.

3. In a stamp of the class described, a stamp-head having a stud projecting therefrom, the base of said stud being of irregular form in cross section, a washer having an opening complemental to and fitting over said stud base and having a spur projecting laterally therefrom, a fiat spring handle having an opening for rotatably receiving said stud and having a semi-circular series of apertures concentric to said opening into any one of which .said spur may be projected, a washer encircling the stud overthe handle and covering said apertures, and a nut threaded to the stud to clamp said parts together. 7

In .testimony whereof, I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
